Influences of sodium hexametaphosphate on interactions of coal and clay particles in flotation

  • 摘要: 通过浮选试验、Zeta 电位测试、吸附量试验和扩展的DLVO理论计算,考察六偏磷酸钠对浮选中煤泥与黏土颗粒间相互作用的影响,研究六偏磷酸钠的作用机理。结果表明:高岭石含量较多时会对煤泥浮选产生不利影响,高岭石含量达到20%,精煤回收率降低18.70%;低用量的六偏磷酸钠会抑制高岭石上浮而对煤影响较小,高用量的六偏磷酸钠会失去选择抑制性;六偏磷酸钠用量为1000g/t时,能使煤和高岭石的Zeta电位分别从-25mV、-39mV移至-32mV、-57mV,增强了颗粒间静电排斥作用;同时,六偏磷酸钠水解形成的大分子吸附于高岭石表面,当颗粒相互靠近时产生较强的排斥力,增强了颗粒之间的空间稳定化作用能。
